شناسایی بهترین ترکیب مالچی و زمان کاشت جهت انجام هیدرومالچینگ و تأثیر این خصوصیات بر برخی صفات کمی و کیفی چمن

Turfgrass is important in urban landscape and by considering that organic matter has a important roll in improving physical and chemical soil characteristics using an organic matter instead of manure and MSW seems necessary .in this research the possibility of using new method of culture such as hydromulching (i.e. mixing seed, organic matter, water, and fertilizer and then distributing it) spent mushroom compost (SMC) has done .for these reason we use two level of SMC 6- month old and one –year old .in two time ,spring and autumn .the experiment design as a factorial Randomized Complete Block Design with 3 replications .Germination ,establishment ,uniformity ,density ,color was measured .results showed that SMC is better than manure especially 6-month old SMC as it is than one-year old SMC .in the spring establishment and germination is better . So using hydromulching by 6-month compost in spring is recommended.
